will occur to adjoining landowners. The drainage way to be affected is crossed by <br />the 110' F1 Haul Road embankment, which will be removed upon the cessation of <br />mining. The road was constructed prior to August 3, 1977. The following <br />stipulation upon the original permit remains in effect: <br />STIPULATION 17 <br />THE EMBANKMENT MUST BE INSPECTED ANNUALLY, OR WITHIN <br />10 DAYS FOLLOWING A STORM WHOSE BACKWATER ELEVATION <br />EXCEEDS THE ELEVATION OF 6941.1 FEET ABOVE SEA LEVEL (10-YR, <br />24-HOUR MAXIMUM STORM EVENTS PROJECTED BACKWATER <br />ELEVATION), BY A QUALIFIED GEOTECHNICAL ENGINEER OR <br />ENGINEERING GEOLOGIST. A LETTER OF CERTIFICATION CONTAINING <br />THE RESULTS OF THAT INSPECTION MUST BE SUBMTI"I'ED TO THE <br />DNISION WITHIN TWO WEEKS FOLLOWING THE INSPECTION. <br />(4.03.1(4)(a)(I)), (2.08.5(d)). <br />The applicant has made a demonstration, based on site specific precipitation rates, <br />percent of grade, and soil properties, that use of altemative specifications for culvert <br />and bridge sizing will not result in increased erosion. The Division, therefore, <br />approved the use of the altemative specifications for the haul road culverts. The <br />culverts were located such that drainage is routed to existing major drainage ways <br />which aze incised to bedrock. (4.03.1(4)(e)(vi)). <br />Seneca proposes to narrow 8.9 miles of haul roads to a width of 20 feet in <br />conjunction with the postmining use. These roads are intended to take the place of <br />jeep [rails that existed in the azea prior to mining. The location of the postmining <br />roads are depicted on Exhibit 12-9. Seneca has not adequately addressed all of the <br />road retention requirements of Rules 2.05.4(2) and 4.03.1(1)(f). Therefore, the <br />Division deems it appropriate to te~aln the following stipulation: <br />STIPULATION 32 <br />APPROVAL OF THE POSTMINING ROAD RETENTION DEPICTED ON <br />EXHIBTI' 12-9, IS CONDITIONED ON THE SUBMITTAL OF A DETAILED <br />RECLAMATION PLAN IN ACCORDANCE WTI'H RULE 2.05.4(2), AND A <br />REQUEST FROM THE LANDOWNER IN WRITING THAT THE ROAD IS TO <br />BE LEFT OPEN FOR FURTHER USE. <br />IS <br />
